To all whom it may concern,.-

e it known that I, EDWARD J. FENDERSON, a citizen of the United States, `residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Spindles for Spinning-Machines, of which the following is a specification.

My invention relates to spindles for spin- [o ning-machines and has for its object to enable such spindles to run steadily at a high rate of speed without being affected by the lateral pull of the driving-band on the whirl. Usually the whirl is rigidly attached to the spinl 5 .dle concentrically therewith and every variation in the tension of the driving-band has a tendency to cause a lateral motion of the whirl and spindle which tendency is resisted by the spindle-supports as'bolsters and steps, 2o but as the spindle-supports and the bearingsurface ofthe spindle become worn the disturbing effect of the driving-band becomes greater. To obviate this effect of the drivlng-band on the spindle, I make the Spindle and whirl in separate parts and support them lndependently of each other, so connecting them that arotation of the whirl will prod uee a rotation of the spindle, whilea slight lateral movement of the Whirl is not communi- 3o cated to the Spindle.

1n the accompanving drawings, Figure l, is an isometric View of a part of aspindle-rail, thebolster or spindle-support, the spindle and whlrl, constructed in accordance with my in- 5 vention, a bobbin and cop on the spindle and the hook which prevents the Spindle from being lifted in dofling; Fig. 2, a front elevation l of a part of the spindle-rail and bolster-case,y

the nut which retains the bolster-case in the 4o rail, the bolster, a part of the spindle and the hook and a central vertical section of the sleeve which forms the lower bearing of the bobbin, the iiange 'of Said sleeve, the Whirl and the upper part of the bolster-case; Fig.

3, a plan of the Spindle and bolster-case and of a part of the spindlerail; Fig. 4, a central vertical section of the bolster-case, bolster, whirl, sleeve-bearing and an elevation of the body of the spindle.

5o The bolster-case A iS supported in the Spin- ,dle-rail B in a Well known manner, said `bolster-case having an enlarged head or upper end @which rests upon the spindle-rail, the latter being clamped between Said head o, and 4a nut 0, which turns on a threaded portion a2 of the bolster-case against the under side of y Said spindle-rail. Within a vertical Opening in the bolster-case is secured the bolster C, ,the same having a centralvertical opening c to receive the lower partof the spindle D which 4has a running fit therein in the usual manner.v Y

The body of the spindle D is of the usual form and is made in a separate piece from ythe whirl E, but is provided with the sleeve d', whichl usually conneetssaid spindle and whirl, Said sleeve serving as the lower bearing of Ythe bobbin F, in the usual manner. If desired, the bolster C may extend up into said sleeve d in a well known manner. The lower end of Said sleeve d is provided with an outwardly-extending horizontal projecabout the same diameter as the whirl E, and is provided. with one` or more radial slots cl3 to receive a corresponding number of pins c which project upwardly from the top of the whirl and loosely engage said slots.

The bolster C is provided below its upper end with a shoulder c', represented as a collar or external annular flange, which supports the whirl E, said whirl surrounding the upper part c2 of said bolster above said Shoulder c and being separated from the body of the spindle by said bolster. The Whirl is provided with a band-groove e', to receive the drivingband in the usual manner. It is evident that a rotation of the whirl in the usual manner will rotate the spindle, the iiange cl2 with its radial slots forming one counterpart andthe whirl with its pins e forming the other counterpart of a clutch, but the bolster is so rigid and the pins e are so loose in the slots d3 that any lateral movement of the Whirl caused by the tension of the driving-band is not communicated to the spindle. The hook Gr extends over the flange dg and serves the usual purpose of preventing the spindle from being lifted out of the bolster C in the act of doing the'bobbins and Said hook may be tion cl2 re resented as an annular iange of Soi IOO

turned in the usual manner to allow the spindle and whirl to be removed when necessary.

The top or head a of the bolster-case A is provided, in the usual manner, with a concavity a" to receive oil which flows down through an inclined oil-hole a4 in said bolster-case into an oil-passage a5, formed in either or both of the contiguous threaded surfaces a c3 of the bolster-case and bolster and into an annular space ci' between said bolstercase and bolster below said threaded surfaces and passes through radial holes c4 which enter the central opening c of the bolster to lubricate the bearing-surface of the spindle. As the spindle gradually increases in diameter from its lower end to the top of the bolster the rapid rotation of the spindle will carry the oil to the top of the bolster and throw said oil over the top of the bolster, against the sides of the central opening e2 of the whirl, and said central opening is riiled or provided with a shallow left-hand screwthread, so thatl the rotation of the whirl, which turns in a right-hand direction or with the sun, carries the oil down to thebottom of the whirl and into an annular chamber as in the top of the bolster-case, said whirl being provided with a downhanging annular flange e3 which extends into said annular chamber a in such a manner that oil dripping from said flange e3 and thrown outward by centrifugal force will be caught in said chamber 0.8, from which it passes through the inclined oil-hole a4 which passes through a corner of said chamber, as shown in Fig. 4.

The above described invention is applicable to auyspinning, winding or twisting machine in which the spindle is rotated by a whirl and band and in which it is desirable to prevent a lateral motion of the whirl being com- 4o municated to the spindle. Said invention also allows of the spindle being removed and replaced without removing the band from the whirl or removingthe whirl from its hearing and thereby allows spindles of diifercnt lengths to be used with the same whirl.

I claim as my invention- 1. The combination of` a spindle and a whirl, formed in separate parts, one of which parts has vertical pins, adapted loosely to e11- gage slots with which the other of said parts is provided, with a bolster, having an internal bearing for said spindle and an external bearing for said whirl, as and for the purpose Specified.

2. The combination of a spindle and a whirl, formed in separate parts, said spindle having a fiange provided with slots and said whirl having pins which loosely engage said slots, with abolster, having separate bearings for said spindle and whirl, as and for the pur pose specified.

3. The combination of the bolster, provided with an external shoulder, the spindle, supported in said bolster, and a whirl, surrounding said bolster and supported on said shoulder, said spindle having a flange provided with slots and said whirl having pins, loosely to engage said slots, as and for the purpose speciied.

In witness whereof I have signed this speci- Ication, in the presence of two attesting witnesses, this 16th day of January, A. D. 1892.

EDWARD J. FENDERSON.
